Question

Which has more momentum, a `3kg` object moving at `5m/s` or a `4kg` object moving at `8m/s`?

Answer 1

`p_2 > p_1`

Explanation:

`"Momentum = Mass × Velocity"`

Momentum of first object `= "3 kg" × "5 m/s" = color(blue)"15 kg m/s"`

Momentum of second object `= "4 kg" × "8 m/s" = color(red)"32 kg m/s"`

∴ Momentum of second object > Momentum of first object
